Abstract (en)
In an example, a print head includes a nozzle, a fluid channel to provide printing fluid to the nozzle and a Light Emitting Diode (LED). The LED may emit light to heat printing fluid in the fluid channel causing localised vaporisation of the printing fluid and ejection of a fluid drop through the nozzle.
